I have a VAF computer reading. I know its Volume Air Flow, but I don't know what it is or where its located. help!

code p 0102 refers to mass air flow(MAF) sensor /volume air flow (VAF) sensor --low input===causes --wiring short to ground ---MAF/VAF sensor ---ECM
check wiring for insulation problems or broken connections
replace the MAF sensor

code p 102 refers to mas air flow (MAF) sensor/ volume (VAF) sensor ---low input===causes --wiring short to ground --MAF/VAF sensor ---ECM
code p 103 refers to MAF/VAF sensor ---high input====causes --wiring short to positive ---MAF/VAF sensor---ECM

code p0102 refers to mass air flow (MAF) / volume air flow(VAF sensor-- low input===causes --wiring short to ground---MAF/VAF sensors---ECM
I would replace the MAFor VAF sensor after having each one tested to find the faulty unit.

clean or replace the MAF/VAF senspr

MAP = mass air pressure, Baro is atmospheric air pressure ( as in barometer), VAF = volume air flow and MAF = mass air flow . The baro sensor alters the air fuel mixture for varying altitudes that the vehicle can travel through. IE from flat plains at sea level to over the rockis.. The VAF sensor measures the volume of air passing through the air intake . The MAF measures the combination of volume and the density of the air flowing through the air intake to adjust the air fuel mixture as cold air is more dense and requires more fuel to burn completely. The MAP measures the vacuum in the manifold after the throttle control to adjust the air fuel mixture in over run situations so that the car will not backfire. All these sensors continually supply input to the ECM which continually compares them with the O sensors and adjusts the injector pulse to ensure complete burn of the mixture in all situations and engine rpm's.

Those sensors are actually connected to your air intake pipe just after your air filter. They're just plug and play sensors.
